The Palais des congrès de Montréal is a convention centre in Montreal's Quartier international at the north end of Old Montreal. Its borough is Ville-Marie. Construction began in 1977 and completed in 1983; the Palais opened on 21 May 1983.[1][2] Victor Prus designed the original building.[3]

Some of the land for Palais des congrès was expropriated from Chinatown, Montreal,[4] along with building of Complexe Guy-Favreau. Plans to expand the Palais began in 1997.[5] It was expanded from 1999 to 2002, doubling its capacity from 92,000 square metres (990,000 sq ft) to 184,000 square metres (1,980,000 sq ft).
